I understand why you want to "push" him to finish the 6C, but just look at when this project was started.
I've started working on my red Sprint three years ago and I'm only half way there !
Eddie spent almost 9 years to complete his V8 Sud !
I know its none of my business, and I dont know what your relationship is with Philip, but I would never feel let down if he wants to lay low for a while, or even abandon the project if he feels like it.
The reasons why he is doing this may be from economical, to household, and even to lost of interest !
But whatever this reason is, personally I wouldnt feel let down in anyway and I respect his decission.
I too would like to see this project finished, but its not my project, not my pocket, not my life, so I would never judge Philip for his desission.
As far as I'm consirned, Philip may finish this project today, or after 10 years or sell it or scrap it if he wants to.
That doesnt define who he is and it doesnt give me the right to tell him off !
Thats my opinion even though I wasnt asked for it.
Philip my appologies, I know I'm not your lawyer, but as you probably know by now, sometimes I cant keep my mouth shut
